Applications:

A new option for shoe material foaming: MT-4, a universal foaming agent for blow-molding and injection-molding shoes. As an upgraded chemical foaming additive, MT-4 is specially developed to meet the diverse needs of modern footwear production, supporting both blow-molding and injection-molding processes for various shoe materials such as EVA, TPR, PVC, and rubber. It features a moderate decomposition temperature, stable gas output, and fine, uniform cell structure, effectively avoiding common defects like collapse, pinholes, and uneven foaming. With excellent compatibility with different polymer matrices, it ensures smooth processing, stable sizing, and consistent product quality. MT-4 delivers high foaming ratio and lightweight effect, reducing material density and production costs while enhancing the flexibility, cushioning, and durability of shoe soles and uppers. It is low-odor, eco-friendly, and compliant with mainstream footwear industry safety standards, replacing traditional foaming agents to improve surface finish and dimensional stability. Suitable for sports shoes, casual shoes, slippers, and safety footwear, MT-4 simplifies production debugging, boosts efficiency, and helps manufacturers achieve high-quality, cost-effective foamed shoe products with reliable performance across batch production.
